Abstract
A display panel includes: a base layer; a pixel defining layer on the base layer and having an emission opening; a partition wall including: a first partition wall layer on the pixel defining layer; and a second partition wall layer on the first partition wall layer and having a partition wall opening corresponding to the emission opening; a light-emitting element in the partition wall opening and including an anode, an intermediate layer, and a cathode contacting the partition wall; and an auxiliary electrode on the light-emitting element and extending along a first inner surface of the first partition wall layer and a lower surface of the second partition wall layer.
Claims20
A display panel comprising:
- a base layer;
- a pixel defining layer on the base layer and having an emission opening;
- a partition wall comprising:
- a first partition wall layer on the pixel defining layer;
- and
- a second partition wall layer on the first partition wall layer and having a partition wall opening corresponding to the emission opening;
- a light-emitting element in the partition wall opening and including an anode, an intermediate layer, and a cathode contacting the partition wall;
- and
- an auxiliary electrode on the light-emitting element and extending along a first inner surface of the first partition wall layer and a lower surface of the second partition wall layer.
A display panel comprising:
- a base layer;
- a pixel defining layer on the base layer and having an emission opening;
- a partition wall comprising:
- a first partition wall layer on the pixel defining layer;
- and
- a second partition wall layer on the first partition wall layer and having a partition wall opening corresponding to the emission opening;
- a light-emitting element in the partition wall opening and including an anode, an intermediate layer, and a cathode contacting the partition wall;
- an auxiliary electrode on the light-emitting element;
- and
- a lower encapsulation inorganic pattern on the auxiliary electrode,
- wherein the lower encapsulation inorganic pattern directly contacts the auxiliary electrode.
A method for manufacturing a display panel, the method comprising:
- providing a preliminary display panel including a base layer, a pixel defining layer on the base layer, a first preliminary partition wall layer on the pixel defining layer, and a second preliminary partition wall layer on the first preliminary partition wall layer;
- forming a first partition wall layer and a second partition wall layer in which a partition wall opening is defined by etching the first preliminary partition wall layer and the second preliminary partition wall layer;
- forming a light-emitting pattern and a cathode contacting the first partition wall layer in the partition wall opening;
- and
- forming, on the cathode, an auxiliary electrode extending along a first inner surface of the first partition wall layer and a lower surface of the second partition wall layer.
